All Implemented Interfaces:

Enclosing class:

TransactionOptions

public static enum TransactionOptions.TransactionType
extends Enum<TransactionOptions.TransactionType>

The type of transaction. With the type you have influence on how much guarantee you get when a member crashes when a transaction is committing.

Enum Constant and Description
LOCAL Unlike the name suggests, local is a two phase commit.
TWO_PHASE The two phase commit is more than the classic two phase commit (if you want a regular two phase commit, use local).

Enum Constant Detail

TWO_PHASE

public static final TransactionOptions.TransactionType TWO_PHASE

The two phase commit is more than the classic two phase commit (if you want a regular two phase commit, use local). Before it commits, it copies the commit-log to other members, so in case of member failure, another member can complete the commit.

LOCAL

public static final TransactionOptions.TransactionType LOCAL

Unlike the name suggests, local is a two phase commit. So first all cohorts are asked to prepare if everyone agrees then all cohorts are asked to commit. The problem happens when during the commit phase one or more members crash, that the system could be left in an inconsistent state.

Method Detail

values

public static TransactionOptions.TransactionType[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (TransactionOptions.TransactionType c : TransactionOptions.TransactionType.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static TransactionOptions.TransactionType valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

id

public int id()

getByValue

public static TransactionOptions.TransactionType getByValue(int value)
